Product Description
Flap valve / Check valve / flap gate
Flap valve which depends on its gravity and pressure difference inside and outside and shoot the door, open and close automatically to achieve the effect of overflow and non-return valve devices, including tidal gate valve, check valve or one-way valve.
The main performance parameters:
1. Material: GRP BMC HDPE Cr13 Q235
2.Temperature: -20°C-60°C (requirements under the maximum design 3.temperature 120 °C flap valve)
4. Working pressure: 1-1.6MPa
5.Opening angle of the cover: >75°
6.Closed time: <2s
7. Open water level:
(1).GRP cover shoot inside and outside the door open when the water level difference of ≥ 40mm
(2). HDPE cover shoot inside and outside the door open when the water level difference of >5mm
The open water level associated with the flap valve's open angle weight, diameter size of the relevant. The open water level can be designed according to user needs.
8. Proportion: GRP flap valve 1.6¬-1.9 g/cm3
HDPE flap valve 0.94-1.17g/cm3
9.Save energy: ≥10%
10.Design head: ≤15m( HDPE flap valve ≤5m)
flap valve
Glass fiber and fabric reinforced polymer composites flap valve basic characteristic
1. Excellent mechanical properties, physical properties
This material density is usually 1.8-2.1g/cm which is about steel 1 / 4. Tensile strength is 160-320 MPa. Specific strength achieves 100-168. (The physical properties shown in Table 1) Coefficient of thermal expansion similar to steel, thermal conductivity is only 0.5% of steel. It is a good thermal and electrical insulation material.
2. Chemical resistance, long service life
A polymer matrix composite material with special chemical resistance in the corrosive medium shows that other materials can not match the superiority of. No recycling value.
3. Design flexibility, product mix performance
It can be enhanced by changing the resin system or material to adjust the physical and chemical properties of the product to suit the needs of the media and working conditions. Through structural layer thickness, layer design and product design to adjust the carrying capacity of the product. Made the performance of different pressure and some special products, which are isotropic metal materials, can not be compared with.
